Agree; those users will need a MMC_CAP_RUNTIME_PM (or maybe call it with the capability it really stands for which is something like MMC_CAP_POWER_OFF_CARD). But I want to be positively sure we have such users (or is it that obvious?). How is the sd8686's reset line manipulated on other platforms ? Or is the sd8686 usually just kept powered on after boot ? I'm looping in libertas-dev.
